I have an Acer Aspire One (named Ass-Pyre, of course) in a drawer somewhere, which I presume still works. Last time I can remember using it was when I took it to Seattle in 2013. Round the house, it got quickly replaced by a Nexus 10 tablet, which still sees daily use. It's getting a bit long in the tooth now, but still holds up.
I looked at what the modern replacement would be, and the options seem to be to spend 1-200 quid on something that's a bit faster, with more cores and a more recent OS, but a worse screen than the Nexus 10, or spend about 400 quid (which is pretty much what I paid for it) to get a decent screen and the faster processor, etc.
